Because measurement is always in progress, we may be critical to your success.
The Letton Hall Group is an independent, deep knowledge team of experts in oil and gas flow. By advancing applications of measurement technology, we make measurements work for our clients’ business objectives.
From drilling to production to transportation and distribution, the oil and gas industry is in the business of processing multi-component fluid systems. To do this successfully, these fluids must be quantified – as they come in, and as they go out. Optimizing the process requires measurement.
At the Letton Hall Group, we help our clients get the most effective measurements they can to realize their goals. No job is too small or too big. Whether the need is routine surveillance, or complying with standards or regulations, or developing technology beyond current capabilities, we are our clients’ trusted advisor and project team.
